The Muir Woods Shuttle Tour is the only tour that stays the longest in Muir Woods (at 90 minutes) and stops at the majestic Marin Headlands. Further, this tour is the only Muir Woods tour that uses a Separate Tour Guide from Driver. The Ferry/Bay Cruise on this tour is the nicest given that the ferry goes right by Alcatraz to get back to the Ferry Building. The Ferry Building is a great place to start the tour!
